case MYSQL_TYPE_VAR_STRING:
convert_to_string_ex(stmt-param.vars[i]);
stmt-stmt-params[i].buffer = Z_STRVAL_PP(stmt-param.vars[i]);
stmt-stmt-params[i].buffer_length =
strlen(Z_STRVAL_PP(stmt-param.vars[i]));
break;
php-5.0.5/ext/mysqli/mysqli_api.c:574
This line is the problem, you can not use strlen to read the length of
binary data, or this convert_to_string_ex() function destroys the
data.
Kind regards

Hello,
i have a hint for you: The size inserted into the database is exactly
the size, that strlen() returns, BUT: strlen stops on the first \0 and
in a real binary file, this sign can be everywhere, not just at the end.
In your case, i
found this:
php-5.0.5/ext/mysqli/mysqli_api.c:161
case 's': /* string */
bind[ofs].buffer_type = MYSQL_TYPE_VAR_STRING;
bind[ofs].buffer = NULL;
bind[ofs].buffer_length = 0;
bind[ofs].is_null = stmt-param.is_null[ofs];
I tried this, and i found out, that it works with
MYSQL_TYPE_VAR_STRING, but you have to specify the length. If i insert
the right lengt, everything works as expected.
So you just have to define the length for the data that is in the bound
variable.
Kind regards

Well, i allready tried this:
?php
mysqli_connect(..);
mysqli_select_db(..);
$s =
file_get_contents('/usr/portage/distfiles/vim-runtime-20050601.tar.bz2');
$one = 1;
$two = 2;
$q = 'INSERT INTO dbfs_data_chunk VALUES (?,?,?)';
$stmt = mysqli_stmt_init($GLOBALS['CONN']);
mysqli_stmt_prepare($stmt,$q);
mysqli_stmt_bind_param($stmt,'iis',$one,$two,$s);
mysqli_stmt_execute($stmt);
mysqli_stmt_close($stmt);
exit;
?
Exaclty the same problem.
Fix it.
Kind Regards

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
from http://www.php.net/mysql_stmt_bind_param
Character Description
b corresponding variable is a blob and will be send in
packages
For sending a blob in packages, you have to use
mysql_stmt_send_long_data. If you don't want to do this (e.g. your data
doesn't need escaping and is max_allowed_package) use type s
(=string).
